• Co/TiO2 catalyst has been activated at 350 °C by diluted CO and H2 respectively.
• Activation with CO produces a more stable and active catalyst at extended TOS.
• Activation with CO leads to higher selectivity and production rate for C5 + hydrocarbons.
Co/TiO2 catalyst activation for Fischer–Tropsch (FT) reaction by CO in comparison to H2 has been performed. The catalyst, prepared by incipient wetness impregnation, has been characterized using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) analyses after separate reduction using CO and H2 respectively. Temperature programmed reduction (TPR) analyses were also conducted to study the reduction behaviour of the catalyst in presence of H2 and CO respectively. CO improved catalyst reduction and produced a more stable and active catalyst with higher selectivity and yield for C5 + hydrocarbons at extended time-on-stream.
